In this chapter, we discussed what reactive programming is and implemented a bare-bones reactive framework, and used it to implement a demo program to help us get a handle on the concepts. We looked at the Reactive Extensions for Python, and used them to re-implement our zoo demo. We finished by looking at some of the broader possibilities of the Rx framework.
In the next chapter, we'll look at microservices, which are very small server processes that are meant to work together to create the desired results.
